The Front Box Squat with barbell is a powerful lower-body compound exercise that primarily targets the quadriceps, glutes, and core. Using a box allows for more controlled squat depth, maintains proper form, and emphasizes correct movement patterns. This movement is excellent for improving squat technique—one of the key CrossFit exercises—increasing functional strength, injury prevention, and explosive muscle development.
